    Answer:

    34

    8

    Step-by-step explanation:

    1/2bc – 6ac + 2ab

    (1/2)(-1)(-3) – (6)(2)(-3) + (2)(2)(-1)

    (1/2)(4) – (-36) + (-4)

    2 + 36 – 4

    34

    1/4(ac)² + 1/6ac

    (1/4)[(2)(-3)]² + (1/6)(2)(-3)

    (1/4)(-6)² + (1/6)(-6)

    (1/4)(36) + (-1)

    9 – 1

    8
